In the future, where most humans are born in the lab, Millicent is a natural born. That doesn't mean her parents weren't selected with great care, and she certainly wasn't conceived the old fashioned way, but she's a natural. Now Millicent has been selected as one of the few women allowed to bare her own child, but she won't get to keep it of course.
Motherhood can be tricky. Moxidone may have made a mistake taking someone of Millicent's abilities and turning them into a breeder. Maternal instincts can be deadly.
This is a great book. Very highly recommended.
